Patent FR-2331904-A1 (FR)
Title: Automatic synchroner for group of diesel alternators - uses two high precission frequency voltage convertors to pass signals into mixer to feed resulting error signal into motor regulator
Inventor: THOMAS PHILIPPE
IPC: H02J3/42
Filed: 1975-11-17
Abstract: The automatic synchronising method uses the frequency of the network whose voltage is available at the terminals of a voltage transformer (I). The frequency of the voltage at the secondary of the alternators transformer (I) is used to indicate the speed of the diesel alternator group. The two signals are introduced into two identical high precision frequency voltage convertors (21, 2) having low drift as a function of time. The signals emanating from each convertor are compared in a mixer (3). The resulting error signal is fed into an electrical speed regulator (4) which drives the motor regulating device.

Title: Double-pass rectifying still esp. for cider - with superimposed tanks and external press.-controlled connecting tube
IPC: B01D3/00
Filed: 1975-12-08
Abstract: Double-pass rectifying still comprises two superimposed tanks sepd. by a partition. The tanks are connected by an external pipe with a 3-way tap so that the cider can be passed from the upper to the lower tank or the contents of the latter can be emptied when distn. is complete. Heat is provided by the hearth. The upper tank is connected by pipe to the condensn. circuit with its heat exchanger, the condenser with its coil and the outlet for the condensate. The descending portion of the tube opens in the base of the upper tank through inclined orifices on the inner edge of the annular tube. The valve is intended to unprime the tube when the press. differences in the tanks are such that the liq. from tank can be sucked into tank. As the distn. proceeds, the liq. in tank is passed into tank and tank refilled with cold material, the hot liq. going through tube. At this moment the runnings from the orifice immediately show an increase in the alcohol content from 16-35 degrees. Distn. is continued during this second heating until the alcohol content at the outlet has come down to the required level. Still increases the amt. of vapours produced without overheating the liq. an avoids any splashing of the liq. into the upper tank or condens. circuit during the boiling. The rotation of the liq. in the upper tank prevents deposits and assists evapn. The amino acids are preserved and the prod. has a conc. aroma.

Title: Measuring overall length traffic stream in road section - uses charge and discharge capacity of capacitor in circuit detecting input and output rates
IPC: G08G1/065
Filed: 1976-06-02
Abstract: The method is for measuring the total length of a traffic stream between two points in a road section. The road section has an input point and an output point. The first stage consists of measuring the input rate of vehicles at the input point. During this first stage the absence or presence of vehicles at the output point is detected. During a second stage, from the output detection during the first stage, is established the possible or impossible flow data. In a third stage a correlation is made between measured data and calculated data. At the input point a first detector (11) detects the presence of a vehicle. A control circuit (12) associated with this first detector sends the data to a remote pulse shaping circuit (13) and a current generator (14). This circuit (11) sends to a capacitor (15) a fixed duration pluse for each vehicle which passes the first detector.

Title: Cast refractories with very low porosity - obtd. using high velocity gas jet to inject molten metal oxide(s) into mould
IPC: C04B35/653
Filed: 1977-01-19
Abstract: Dense refractory materials are made with very low porosity by casting molten metal oxides, the metl is dispersed by a high velocity gas stream so the particles are fed at high energy as a jet into the mould. The particles may be spun into the mould and the distance between the mould and jet gradually increased for gradual or stepwise redn. in the energy of the particles; and/or in the later casting stage, an expansion agent can be added so a dense casting skin is followed by a foamed or expanded core. The molten oxides may have a specific m.pt. and be held in a gas stream until they solidify; alternatively, a melt with no specific m.pt. may be used. The gas stream may contain seed crystals, and the jet sprayed onto a slowly rotating roll or other surface to form a thin solidified layer which is continuously removed and crushed to size. The pref. gas stream uses air, nitrogen, Ar, O2, CO2 or their mixt. Used for the mfr. of refractories, insulation for high temp. use, or abrasive materials.

Title: Underground fuel tank overfill prevention - has valve which is actuated by diaphragm controlled by fluid level
IPC: F16K21/18
Filed: 1977-06-20
Abstract: An underground tank for storing flammable liquids has a diaphragm valve(4) with a lower chamber(1) connected to the supply line (7). The upper chamber (2) is connected through a regulating valve(Rs) to a pair of float valves (V1, V2) inside the tank.
